Ali Mohammad Pur	8f722302d9	LibRegex: Use a match table for character classes ... Generate a sorted, compressed series of ranges in a match table for character classes, and use a binary search to find the matches. This is about a 3-4x speedup for character class match performance. :^)	2021-10-03 19:16:36 +02:00
Ali Mohammad Pur	bf0315ff8f	LibRegex: Avoid excessive Vector copy when compiling regexps ... Previously we would've copied the bytecode instead of moving the chunks around, use the fancy new DisjointChunks<T> abstraction to make that happen automagically. This decreases vector copies and uses of memmove() by nearly 10x :^)	2021-09-14 21:33:15 +04:30
Ali Mohammad Pur	246ab432ff	LibRegex: Add a basic optimization pass ... This currently tries to convert forking loops to atomic groups, and unify the left side of alternations.	2021-09-13 14:38:53 +04:30
